Chapter 1 Product Overview
Rear-Panel Description
Figure 1-15 Bandwidth Utilization for the Catalyst 3550-48 Switch
shows the bandwidth utilization percentages displayed by the LEDs
on the Catalyst 3550-24-FX switch. If all port LEDs and GBIC LEDs on the
switch are green, the switch is using 50 percent or more of its total bandwidth. If
port LEDs 1 through 24 and GBIC port 1 LED are green, the switch is using
between 25 and 50 percent of its total bandwidth. If port LEDs 1 through 24 are
green, the switch is using 12.5 to 25 percent of its total bandwidth capacity, and
so on. Amber LEDs indicate the peak utilization of the switch over the last 24
hours.
